Constructor and Description
TCustomObjectHash() FOR EXTERNALIZATION ONLY!!!
TCustomObjectHash(HashingStrategy<? super T> strategy) Creates a new TManualObjectHash instance with the default capacity and load factor.
TCustomObjectHash(HashingStrategy<? super T> strategy, int initialCapacity) Creates a new TManualObjectHash instance whose capacity is the next highest prime above initialCapacity + 1 unless that value is already prime.
TCustomObjectHash(HashingStrategy<? super T> strategy, int initialCapacity, float loadFactor) Creates a new TManualObjectHash instance with a prime value at or near the specified capacity and load factor.

TCustomObjectHash

public TCustomObjectHash()

FOR EXTERNALIZATION ONLY!!!

TCustomObjectHash

public TCustomObjectHash(HashingStrategy<? super T> strategy)

Creates a new TManualObjectHash instance with the default capacity and load factor.

TCustomObjectHash

public TCustomObjectHash(HashingStrategy<? super T> strategy,
                         int initialCapacity)

Creates a new TManualObjectHash instance whose capacity is the next highest prime above initialCapacity + 1 unless that value is already prime.

Parameters:

initialCapacity - an int value

TCustomObjectHash

public TCustomObjectHash(HashingStrategy<? super T> strategy,
                         int initialCapacity,
                         float loadFactor)

Creates a new TManualObjectHash instance with a prime value at or near the specified capacity and load factor.

Parameters:

initialCapacity - used to find a prime capacity for the table.

loadFactor - used to calculate the threshold over which rehashing takes place.
